I have to say this. I am completely surprised by the rating of this anime. People dropped it too early. The first few episode may seem boring. But before you dropped it, try to continue watching it up to at least episode 6 and then you can reconsider. A bit of hint: there is a background plot. And this anime is not as docile as it seems from the first few episodes. The world building and the intensity of the story goes up every episode. Sure at this point this anime just got overshadowed by some other big animes this season. But the score shouldnot be this low.
